Postharvest quality of ‘Prata Catarina’ banana submitted to different mechanical damages and refrigerated storage

Abstract

The aim of this study was to evaluate the effect of mechanical damages caused by impact, cut and abrasion on the quality of ‘Prata Catarina’ banana subjected to cold storage (14°C±1°C and 84%±5% RH for 21 days). The fruits were from a commercial orchard in the city of Limoeiro do Norte-CE. The experiment was conducted in a completely randomized design in split plot in time, taking up the samples in portions over time and in the subplots the four treatments: control or absence of mechanical damage (T1), impact (T2), abrasion (T3) and cut (T4), with 4 replicates of 2 fruits. Damages by impact and abrasion were the ones which provided the highest speed of ripening, and the damage caused by impact provided greater polyphenoloxidase enzyme activity. ‘Prata Catarina’ bananas that suffered no damage can be marketed until 21 days of storage (14°C±1°C and RH 84%±5%), without loss of quality.
